Mixtures are further classified as either homogenous mixtures or heterogeneous mixtures based on their composition. Compounds, on the other hand, are also pure substances when two or more elements are combined chemically in a fixed ratio. The variety of things with different sizes and shapes in our universe is Mixtures can be of either homogeneous or heterogeneous. Mixtures are formed when two or more substances (elements or compounds) mix together without participating in a chemical change.

A mixture may be homogeneous or heterogeneous, does not have fixed composition,have fixed melting and boiling point. Characteristics of Mixtures. 1) Those mixtures in which the substances are completely mixed together and are indistinguishable from one another. The composition of a compound is fixed,the constituents are present in fixed   proportion by mass. Gun Powder is a mixture of potassium nitrate,sulphur,charcoal. The various substance present in a mixture are called as its constituents or components. Feedback. Thus, the forces, which hold the constituents of a mixture together, are … Let us now look at some of the characteristics of pure substance. Example: The properties of air are average common properties of nitrogen and oxygen. No chemical reaction takes place amongst the constituents of a mixture. MCQs from CBSE Class 9 Science Chapter 1: Matter in Our Surroundings 1. The size of solute particles in a suspension is quite large. 1. Colloids are a heterogeneous mixture consisting of two phases dispersed phase and dispersing phase. What are elements, compounds & mixtures (pg 25,26,27 & pg 14 and 15 till BBQs) 1stLecture. 6) They can be homogeneous or heterogeneous. Answer: A sample of matter containing only one substance is called a pure substance. Their constituents can be separated easily using physical methods. In this video I defined and explained the term compound, mixture and their properties.
